Summary statistics are essential tools in the field of statistics that provide a concise overview of a dataset. They help in simplifying complex data by presenting key numerical values that represent the main characteristics of the data. Common summary statistics include measures such as the mean, median, mode, range, and standard deviation. These statistics allow researchers and analysts to quickly understand the central tendency, variability, and distribution of the data, facilitating informed decision-making. However, it is crucial to interpret summary statistics carefully, as they may not capture the full story behind the data, especially in the presence of outliers or skewed distributions.
